ATTACKER HAD RECORD OF VIOLENCE
Khalid Masood, the man who killed four people Wednesday in an attack with his SUV and knives on London’s Westminster Bridge and near Parliament, was formerly known as Adrian Elms, with a reputation for drinking and an unpredictable temper.
Authorities said Masood was convicted at least twice of violent crimes.
Prime Minister Theresa May said Masood was “investigated in relation to concerns about violent extremism” years ago. But she called him “a peripheral figure.”
